A +(- c) :

a is -1 and c is 3, so it would be:
-1+(-3) = -4

c-(-b) :

c is 3 and b is 2, so it would be:
3-(-2) = 5

b :
b is 2 and there’s no addition or subtraction that needs to be done here

we have -4, 5, and 2 and going from least to greatest it’s : -4 < 2 < 5

so just look at which values gave us those answers and that would be:
a+(-c) < b < c-(-b)

so the final answer is a+(-c) < b < c-(-b)

Answer:

the best way to solve this is to have graph paper, so your numbers and points align. I have a model attached. the first point is hours slept 8. so on your graph go to 8 then across to 83, which is the test score. make a mark to represent this point. do this for all and it will create a line

I think the answer is C) 4x=12 but I am not sure. Please help and explain!!

Dmitriy789 [7]

You are correct, C) 4x = 12.

So, if 4 people are eating 12 pieces of pizza, simply divide 12 by 4 and there's your answer!

12 / 4 = 3 Each person gets 3 slices of pizza.

Answer:49 sec

Step-by-step explanation:

Given

Maximum speed to reach is 183.58 mi/h

Length of course is 5 mi

acceleration rate is defined by 60mi/h in 4 sec

therefore acceleration(a) $=\frac{v-u}{t}$

$a=\frac{60\times 60\times 60}{4}$

$a=54\times 10^3 mi/h^2$

To reach a speed of 183.58mi/h with an acceleration of $54\times 10^3 mi/h^2$

Using equation of motion

v=u+at

$183.58=0+(54\times 10^3)t$

$t=\frac{183.58}{54\times 10^3}$

t=0.00339 hours

t=12.23 s reach maximum speed

To complete course it takes

$s=ut+\frac{1}{2}at^2$

$5=0+\frac{1}{2}\times 54\times 10^3 \times t^2$

t=0.01360 hour

or $t=48.98\approx 49 s$

4. The students in Mr. Michael’s art class are decorating a booth for Harvest Day. They have blue cloth that is 60 inches long,

MrRissso [65]

Length of blue cloth is 60 inches , length of gold cloth is 48 inches and length of white cloth is 72 inches.

a.

As, the length of all pieces are equal, so for getting the greatest possible length of the pieces, we need to find GCF(greatest common factor) of 60, 48 and 72.

First we will factor out all three numbers completely......

$60=2*2*3*5\\ \\ 48=2*2*2*2*3\\ \\ 72=2*2*2*3*3$
